For pager_memcpy you'd still have to set up the fault handling around
the mach_memcpy call, so it remains better for pager_memcpy to have its own
check up front.

Eh, that's only half of it. memcpy is as likely to be inlined in the
bits/string.h magic, or by the compiler. An

I think that fshelp_isowner in libfshelp/perms-isowner.c should be the only
place making this decision. So you can hack that function to print out
details when it makes a negative decision, if it's not convenient to just
debug the filesystem and set a breakpoint there.
There should not be any so

Hi,
I have stressted the libioenvironment a bit today. As this is a fresh
build, there might still be issues that can be contributed to build
weirdness, but it seems unlikely to me.
Sometimes creating a file fails with ENOPERM for no apparent reason.
This is not reproducible, trying again creat

Hi,
Here is the follow-up patch that allows netfs_make_protid to only set errno
on failure. I've followed the examples uses of netfs_make_protid
already in libnetfs, so this should confirm the interface for
netfs_make_protid.
I've included the diff for make-protid as well.
I did a quic

There is no need to always set errno (though you should check all the
callers to make sure--which needed to be done first anyway).

I am pretty dubious about modifying memcpy at this point. There are a lot
of different implementations in libc, and they are being further tweaked
all the time. There are both assembly implementations and inline-macro
implementations, and many of each for all the tiny variants of chip that
exist

This one is incorrect; it changes the established interface of
netfs_make_protid, which is that errno is set on error returns.
See, for example, libnetfs/fsys-getroot.c whic

There is a function in utils/w.c called fetch_boot_time (). Moving this
function to a hurd libraries would make it much simpler for people to write
there
own uptime programs for GNU Hurd and any other application that might want to
get the systems boot time, like procfs.

Hi,
I'm curious what types of checks would be in a make check target for the
hurd.
Would have to be run in a sub-hurd to test all the hurd translators and libc
functions? Should the test programs be compiled within that test sub-hurd?

Hi,
Here is my patch that is overzealous in the use of error ;)
I didn't touch any code that was copyrighted UC Berkeley or CMU, nor did
I touch any code that didn't compile already.
This patch includes the previous patch because they are related.
